If you missed one birth control pill, take the missed pill as soon as possible, even if it means taking two pills in one day. Then, continue taking the rest of the pills in the pack as normal. You dont need to use backup birth control in this case. If you missed two or more pills, take the most recent pill you missed as soon as possible, even if it means taking two pills in one day. Discard any other missed pills. Then, continue taking the rest of the pills in the pack as normal. Use backup contraception, such as condoms, for the next seven days. If you missed three or more pills in a row, use backup birth control until your next period and pill pack. If youre unsure what to do, check the information leaflet that comes with your contraceptive pills or contact your healthcare provider for advice.
